SUPERNOVA 2000ez IN NGC 3995
     G. M. Hurst, Basingstoke, England, reports the discovery of an
apparent supernova (mag 16.8) by M. Armstrong, Rolvenden, on a CCD
exposure obtained on Nov. 24.167 UT with a 0.35-m telescope in the
course of the U.K. Nova/Supernova Patrol.  SN 2000ez is located at
R.A. = 11h57m45s.75, Decl. = +32o17'49".1 (equinox 2000.0), which
is 22".5 east and 12" north of the center of NGC 3995.  The new
object was confirmed on images taken by M. Schwartz (0.52-m
telescope; mag 16.9) on Nov. 28.846, by P. Garnavich (Vatican
Advanced Technology Telescope; R = 17.5) on Nov. 29.5, and by
Armstrong on Nov. 30.731.  Garnavich adds that SN 2000ez appears
red and may be extinguished by dust in the host galaxy.  SN 2000ez
does not appear on second Palomar Sky Survey images taken on 1991
Apr. 3 (red plate; limiting mag 20.8) and on 1996 Mar. 17 (blue
plate; limiting mag 22.5), or on CCD images obtained by T. Boles
(1999 Dec. 5) and by the Lick Observatory Supernova Search (1999
May 8).


SUPERNOVA 2000fa IN UGC 3770
     A. Friedman and W. D. Li, University of California at Berkeley,
on behalf of LOTOSS (cf. IAUC 7514), report the discovery with the
0.8-m Katzman Automatic Imaging Telescope (KAIT) of an apparent
supernova (mag about 17.5) on an unfiltered image taken on Nov.
30.5 UT.  SN 2000fa was confirmed (at similar brightness) on an
unfiltered image taken by M. Schwartz with the 0.5-m Tenagra III
automatic telescope on Dec. 1.2.  The new object is located at R.A.
= 7h15m29s.79, Decl. = +23o25'32".5 (equinox 2000.0), which is 5".1
east and 5".6 south of the nucleus of UGC 3770.  KAIT images of the
same field taken on Nov. 24.5 (limiting mag about 18) and 17.4
(limiting mag about 19.0) showed nothing at this position.


SUPERNOVA 2000el IN NGC 7290
     T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrum of SN
2000el (cf. IAUC 7523, 7531), obtained by P. Berlind on Nov. 25.13
UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST
spectrograph), shows it to be a type-II supernova several days
after maximum light.  The spectrum consists of a well-defined
continuum with superposed P-Cyg lines of hydrogen and Ca II.
Narrow H-alpha emission superposed on the spectrum of the supernova
indicates a recession velocity of 2970 km/s for the host galaxy.
The expansion velocity derived from the minimum of the H-beta line
is 4200 km/s.
